I IV V E N TOR Lucia/z fli'il afirandt ATTORNEYS face of the rib 11 in the said main sight. Vertical and transverse bars 20 extend from the ring 19 and meet at the central portion of the said ring, at which point of meeting of the bars a peep 21 is provided. In operation the cross-bars and central or inner eep 21 a pear as fine lines or shadows and do not 0 struct the view for a uick aim, while they still aid the eye to quic y find the center, and yet the inner peep is distinct enough to allow a more exact aim to be taken when there is time to do so.

The auxiliary sight C may be termed a disk si ht," and the disk sights'are usually made slig tly dishing or convexed and are sprung into place in the main sight. The main sight onl may be used, if desired, as the auxiliary e or disk sights are readily removable. If desired, the auxiliary sight may be in the form of a solid disk 22, as is shown in Fig. 7, provided with a central peep 23, or the auxiliary sight may be constructed as shown in Fig. 8, consisting of a disk 24,

having an angular opening 25 therein, roducin a crotch-sight. The sight is rea ily, quick y, and accurately adjusted vertical y without the assistance of a tool, and it is not atall liable to et out of adjustment. The use of the fine tIiread on the elevating screw or stem l2 and the production of a greater number of apertures 16 in the adjusting-nut will provide for very accurate adjustment. By causing the elevating screw or stem to enter the aperture 13in the breech-bolt or part supporting the sight the sight is prevented from being displaced or knocked sidewise or laterally.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. A gun-sight, comprising a ring-shaped member, having a threaded projection, a nut on the said projection and provided with. a plurality of openings, and a sight held within the ring-shaped member.

2. Ina gun-sight, the combination with the breech bolt, of a ring shaped member provided with a projection, an adjustable member on the projection and engagingthe breech-bolt, a sight within the ring-shaped member, and a spring exerting downward tension on the said ring-shaped member.

3. The combination with a gun havinga vertical opening, of a sight comprising a ringshaped member having a threaded projeetion extending into the opening of the gun, a nut on the threaded projection of the ringshaped member, means for locking the nut in position, and a sight held within the ringshaped member.

4.. In a gun-sight, the combination with the breech-bolt of a gun, of a sight provided with a projection, means on the projection and en aging the breech-bolt for adjusting the said sight, and means for locking the adjustinlg means inposition.

5. n a gun-sight, the combination with the breech-bolt of a gun provided with an opening, of a sight provided with a threaded projection entering the opening of the breecholt, a nut on the'threaded projection and engaging the breech-bolt, and a spring secured to the breech-bolt and to the sight.

6. In a n-si it, the combination with the breecholt oia gun having an opening therein and provided with a lug, of a ring-like sight having athreaded projectionv entering the opening of the breech-bolt, a nut on the threaded projection and provided with a plurality of 0 enin s for receivingthe lug of the breech-b0 t, an a spring secured to the sight and to the breech-bolt.

7. In a the breecholt of a 11 provided with an o enin and a lug ad acent to said opening,

0 a sig t in the form of a ring-like body and having a threaded projection entering the opening of the breech-bolt, an auxiliary sight removably held in the body, a nut on the threaded projection and provided with a plurality of openin s, and a spring having one end secured to t e breech-bolt and its other end to the main sight. 1

8. A gun-sight, comprising a main sight in the form of a ring-like body and 'havin an annular rib on its inner face, and an auxi iary disk sight having an o enin therein, said disk sight being made thm an adapted to be sprung into place in the main sight.

In testimony whereof I have signed my name to this specification in the presence of two subscribin witnesses.
